More particularly, this arrangement prevents the reference points used for the leveling operation from being brought into an incorrect position by a subsequent raising of a track section during the apparatus advance. This advantage is ffurther assured by maintaining the spacing A4 between the foremost tamping unit and intermediate running gear 9 the same as the intermittent apparatus advancing distance X-4.
